I agree on the cat. I was going to mention that . One can only dream. 55 cat would be nice although hard to find moorage. I know the area. Awesome. My buddy is on the north shore landed today. Hope the locals leave his haole ass alone. Lol
He should be ok, just treat others as you would like to be treated and all is good.
I am on the fence about a cat. They are big and nice, but what about in a big storm? I feel safer in a mono that can roll and come back. Docking, as you point out is a big expensive problem, and harder to manuver. I assume its like paying for two boats (double slip) unless you are on an end pier. I'll stick to a mono.
